Bridgestone Blizzak WS90 Winter Tire 245/45R17 99H XL – BMW E/F Series

The core of the WS90's performance advantage lies in Bridgestone's proprietary Multicell compound, which embeds microscopic bit particles throughout the tread. These particles physically micro-scratch the ice surface on contact, while the compound simultaneously absorbs the thin water film that forms between tire and ice—the primary cause of reduced grip. The result is dramatically shorter stopping distances and more confident directional control than conventional winter tires can deliver on glare ice.

Bridgestone engineered the WS90 not just to perform, but to last. Under typical seasonal use—roughly mid-October through mid-April—the WS90 delivers measurably longer tread life than its WS80 predecessor, effectively adding an extra winter season before replacement is needed. The Extra Load (XL) designation means the 99H load and speed ratings comfortably accommodate the additional weight of larger BMW sedans, coupes, and equipped variants without sacrificing handling precision.

Fitment is confirmed for BMW E and F-Series chassis running the 245/45R17 specification, including models like the E82 1 Series, F30 3 Series, and F32 4 Series. No modifications are required—these mount directly on your existing 17-inch wheels and integrate seamlessly with BMW's DSC and ABS systems. If you drive a BMW through real winters, the Blizzak WS90 is the tire that lets the chassis do its job.
